Hi,
Should be there errors and scsi sense codes if your VM data gets corrupted, or is it possible that content of the block itself is corrupted (e.g. bitflip) in such way that on scsi level looks OK, but the data itself is not valid ?
It is happening from time to time that random VM just dies or starts reporting various FS errors, like would you have bad hdd on physical server. This happens only with VMs on FC array while those on iscsi one don't have a problem. Array and san fabric is supposedly OK, so I am looking on server and vmware side if there is anything that would indicate what is going on.
best regards
